COAL SAVING

BY SCIENTIFIC METHODS IN
  THE BOILER HOUSE 

1 COMPLETE HAULAGE INSTALLATIONS |
For COLLIERIES, MINES, QUARRIES, &c.
SPECIALLY DESIGNED TO MEET WORKING CONDITIONS.

New Boiler= Plants.

The average nett working effi-
ciency of new Colliery boiler-plants
erected to-day is only about 60/.
The new boiler-plant designed on
scientific lines will give 75—80X
efficiency, corresponding to an
annual saving of—say 20X, which
goes on for the whole life of the
plant (say 20 years).

We offer you our services as
Specialists in this business with
ten years continuous experience,
including every description of
boiler-plant in almost every
industry.

We are prepared to design for you
a plant on the most up-to-date lines
and supply all drawings, specifica-
tions, and builders’ quantities. Also
advise on the fuel to be used and
the treatment of the boiler-feed
water, and carry out all the chemical
analysis necessary. Further, we
will send you down one of our
trained engineers to instruct your
boiler-house staff in running the new
plant until the maximum efficiency
is obtained.

We shall be glad to explain our
proposition personally or by letter,
and we are prepared to visit your
Colliery free of charge and give you
our opinion of the working of your
boiler-plant.

Winding Engines fitted with
Ferodo-lined Brakes

possess a 50 % greater margin of safety and can be
worked at higher speeds than those fitted with the old
makeshift materials such as wood, leather and hemp.

These relics of an inefficient age have all the short-
comings common to makeshifts. They are adversely
affected by pressure, speed and heat.

Ferodo fabrics give a higher co-efficient of friction, which
enables engineers to raise their standard of production.
